NASAL MASK AND CONTINUOUS POSITIVE AIRWAY PRESSURE TREATMENT DEVICE FOR NOSE

摘要

PPROBLEM TO BE SOLVED: To provide a nasal mask and a continuous positive airway pressure (CPAP) treatment device for the nose wherein leakage is prevented, limiting a relative movement between the nose of a wearer and his face. PSOLUTION: The nasal mask and (CPAP) treatment device for the nose is provided with a nasal cushion 30 which includes a triangle-like frame 32 including a rim 40 to cover the nose of the wearer and a membrane 34 which is more flexible than the frame 32 having a nearly identical shape as the rim 40 and which is fixed to the frame 32 so as to form a seal for a face contacting portion including the exterior surface set apart from the rim 40. When the mask is worn, the rim 40 functions as an end limit for the membrane 34 to deform and come in contact with. PCOPYRIGHT: (C)2004,JPO
